Abstract: 1,172,029. Sealing pipe leakages. SMITHBLAIR Inc. 21 Sept., 1967 [14 Dec., 1966], No. 43084/67. Heading F2P. A leak sealing gasket for disposition between the outer wall of a pipe 20 and the curved band of a pipe clamp 12 comprises a sheet of resilient elastomeric material 10 and a portion of elastomeric material, or semi-rigid moulded plastics material, on the sheet to form a portion 26 of increased thickness, the outer surface of the portion of increased thickness being reinforced or, relatively hard. As shown an armour strip 28 extends between the opposite sides of the sheet over the portion 26 of increased thickness which extends to, or beyond, the opposite ends of the armour strip 28. The portion 26 may be integrally moulded with the sheet 10 or, be formed of a separate double wedge-shaped member (26a) with an embedded armour strip (28a), Figs. 2A, 2B, not shown, the member (26a, 28a) being bonded to the upper surface of the sheet (10) at the desired location. The sheet has two degrees of taper (30, 32), Fig. 4, not shown, to provide a substantially constant thickness of sheet beneath the clamp band 16 within an overlap, e.g. of from 2À5 to 5À5 inches. When the band 16 of the clamp is tightened by bolts 18, the armour strip 28 distributes the clamping force of clamp lugs 14 evenly on to the portion 26. The inner surface 22 is preferably moulded with a grid-like pattern of intersecting ridges 22, and the portion 26 is located nearer to one end of the sheet 10 than the other.

Title: Process for removing formic esters from their mixtures with alcohols
IPC: C07C45/50
Filed: 1966-10-05
Abstract: 1,148,111. Purifying formic esters. RUHRCHEMIE A.G. 5 Oct., 1966 [16 Oct., 1965], No. 44544/66. Heading C2C. Removing a formic ester of an aliphatic alcohol from a mixture of the ester and the said alcohol by heating the mixture with an aqueous solution of an alkali metal salt of a strong organic acid at a temperature in the range 200- 260 C. The alkali metal salt is preferably a formate, acetate or oxalate and may be present in the aqueous solution in a concentration between 1 and 40% by weight. Under the conditions of the process the formic acid component of the esters is converted into gaseous products such as carbon dioxide, carbon monoxide and hydrogen. The process may be carried out in a continuous manner by introducing the mixture to be treated from a container and the aqueous alkali metal salt solution, e.g. from a container or recycled from phase separator, into the bottom of a stationary vertical heated tube, the major part of the tube, preferably 75% of its volume, being filled with the aqueous solution. The organic mixture ascends the heated tube and is passed through a cooler into a separator where gaseous products are removed from the liquid product which is then separated into organic and aqueous phases in a separating vessel, the aqueous phase being re-cycled. Although any mixture containing formic esters together with alcohols and other organic compounds which are inert under the reaction conditions may be used the preferred starting materials are ester/alcohol mixtures obtained by the hydroformylation of an olefin particularly those obtained as residue in the distillation of raw aldehydes formed in the hydroformylation. The treatment of mixtures containing iso- and normal-butyl formic ester and the corresponding alcohol and ether with aqueous sodium acetate, formate or oxalate; of 1, 3-propanediol difoamate and of an oxosynthesis product containing isooctyl formate with aqueous sodium formate is described.

Abstract: 1,184,498. Determining check digits. NATIONAL RESEARCH DEVELOPMENT CORP. .18 Oct., 1968 [3 Oct., 1967], No. 45043/67. Heading G4H. Apparatus for determining the check digit of a number comprises a plurality of groups of selection means, e.g. selector switches, one group for each of the digits of the number, the selector 100 corresponding to the highest significant digit giving a remainder signal which selects one of the next group of switches, these corresponding to the next digit, the selected switch giving a remainder signal selecting one of the next group and so on, the ouput of the selected switch 400-410 of the last group giving an output to indicate the check digit. The check digit is calculated by multiplying each digit by a factor, the units digit by 2, the tens by 3, the hundreds by 4 the thousands by 5 and so on. The sum of all the products is divided by 11 and the remainder is subtracted from 11 to obtain the check digit. The sum of all the products and the check digit will then divide exactly by eleven. The apparatus is arranged to give a remainder for each digit in turn, passing it on to the next. The thousands digit is set up on dial 111 and switch 100 then gives the remainder when the digit is multiplied by 5 and the product divided by 11. The hundreds digit is set up on dial 222, the remainder when the digit is multiplied by 4 and the product divided by 11 appearing on switch 200. However, the remainder from the previous digit must be added and the present remainder adjusted accordingly. The switch 20 (ganged to switch 200) corresponds to a previous remainder of 1; switch 202, of 2; switch 203, of 3, and so on. The appropriate switch 200-209 is selected by the selected output lead of switch 100 and the selected switch then selects an output lead which, in turn selects a switch in the next group 300-310. This group corresponds to the tens digit and gives the remainder of the previous remainder plus the tens digit multiplied by 3, all divided by 11. The remainder signal selects one of the switches in the units group 400-410 which produces a remainder output in a similar way. This output is the 11's complement of the required check digit and the selector switches may be connected to suitable indicators showing the check digit, e.g. a remainder signal on a "2" lead would light a "9" indicator. To check a check digit it is set up on dial 555. One of the selector switches (selected by the output from the selected one of units switches 400-410) then connects to lamp 14 which lights when switch 15 is closed. If the check digit is incorrect, lamp 16 lights. Instead of selector switches diode or transistor logic circuits may be used.

Abstract: 1362828 Snap-action switches WESTINGHOUSE ELECTRIC CORP 30 Sept 1971 [10 Nov 1970] 45567/71 Heading H1N In an enclosed switch-fuse, each fuse 89 is supported in fuse clips 65, 71, and the fuse clip 71 is mounted on a conductive terminal block 73 adjacent an opening 81 in the end wall 19 of the casing, and connector 85, to secure external conductor 87 in block 73, is located between fuse clips 65, 71 so that access to connector 85 through the openable front of the casing is blocked by fuse 89 when this fuse is in position in the fuse clips. As shown, there are two independently operable switch fuses in the casing, both being three pole and both being identical and each having its own door 13 and operating handle 93. For each switch fuse, pivoting handle 93 rotates on inner operator 99, Fig. 5, which pivots operating lever 37 to pivot bar 35, through an overcentre spring mechanism (not shown) to pivot movable contact blades 33 into clip type fixed contacts 31. Blades 33 are connected by flexible conductors 69 and conductors 67 to fuse clips 65. Opposite clip contacts 31 on the two switches are joined by straps 49 which serve as the terminals for external line conductors. Each door 13 is hinged at 21 and interlocked with the casing so that the door cannot be opened when the switch is on. Each interlock comprises a latch 105, Fig. 5, urged by a torsion spring 107, when handle 93 is in the on position shown, so that a hook on latch 105 engages a projection 109 on the side wall of the casing. Movement of handle 93 to the off position causes part 113 of inner operator 99 to engage a part 115 of latch 105 to pivot latch 105 to remove the hook from projection 109 and allow door 13 to open. When the door 13 is latched closed, the interlock can be defeated by a bolt 117, Fig. 6 (not shown), which when rotated frees latch 105 from projection 109 so that door 13 can be opened. If latch 105 is in the latched position and the cover is open then moved to the closed position, a cam surface 119, Fig. 6, engages projection 109 to cam latch 105 clockwise until it has cleared pin 109, when spring 107 urges latch 105 to its latching position. The depth 123, Fig. 6, of latch 105 is such that if handle 93 is in the off position and the door 13 is not fully closed, surface 123 engages projection 109 to prevent latching of latch 105, and part 113 on internal operator 99 engages surface 127 on latch 105 to prevent handle 93 being moved from off to on.
